[0040] Example:

[0041] See also Figure 1 to Figure 4The steel tube laser cutting system in the preferred embodiment of the utility model comprises a support frame 1, a track 2, a clamping device 3 and a laser cutting device 4. In specific implementation, the track 2 can be fixedly connected to the ground, and is arranged on one side of the bottom of the support frame 1, specifically, it can be arranged on the left side or the right side or both sides.

[0042] Furthermore, in the preferred embodiment, a motion device 5 is correspondingly arranged on the track 2, the motion device 5 is matched and connected with the track 2 and the motion device 5 can reciprocate on the track 2. The laser cutting device 4 is connected to the motion device 5, and the laser cutting device 4 can move under the drive of the motion device 5, so that the laser cutting device 4 can move to the part of the steel pipe that needs to be cut and perform targeted cutting on it.

[0043] Among them, Figure 1 As shown, in the preferred embodiment, at least two motion devices 5 are provided, and at least two corresponding laser cutting devices 4 are provided. Arranging multiple motion devices 5 and laser cutting devices 4 allows multiple laser cutting devices 4 to work simultaneously, thereby improving cutting efficiency, and the steel pipe 8 to be cut does not need to be clamped multiple times, which can ensure cutting accuracy and reduce cutting costs.

[0044] Specifically, in the preferred embodiment, the laser cutting device 4 is a mixed gas assisted laser cutting head which can cut two layers of the pipe wall at the same time, so that the required cutting part can be cut only once, thereby improving the cutting efficiency.

[0045] Furthermore, if Figure 2 As shown, in the preferred embodiment, a driving wheel 6 is connected to the top of the support frame 1, and the steel pipe 8 to be cut is placed on the top of the driving wheel 6. In specific implementation, the driving wheel 6 is V-shaped, which can be a V-wheel, and the steel pipe 8 is placed in the depression of the V-wheel. The rotation direction of the driving wheel 6 is the same as the moving direction of the steel pipe 8. For example, the steel pipe 8 enters the support frame 1 in the horizontal direction and moves in the horizontal direction, and the driving wheel 6 also rotates in the horizontal direction. In this way, the hot or cold steel pipe 8 can move straight on the driving wheel 6 without rotating, avoiding cutting of the part outside the preset cutting range during the cutting process, thereby improving the cutting accuracy.

[0046] In addition, if Figure 3 As shown, in the preferred embodiment, the clamping device 3 is connected to the support frame 1, and the clamping device 3 includes a clamping wheel 301, a frame 302 and an adjusting member 303. The frame 302 is connected to the support frame 1, and the clamping wheel 301 is connected to the frame 302 through the adjusting member 303. The adjusting member 303 can adjust the position of the clamping wheel 301, so that the clamping wheel 301 can abut against the top of the steel pipe 8 to be cut, and play a clamping role on the steel pipe 8 to be cut.

[0047] In detail, in the preferred embodiment, the adjusting member 303 is driven to move by the cylinder. In specific implementation, a photoelectric switch can be set to detect the entry and exit of the steel pipe 8, and at the same time control the expansion and contraction of the cylinder to drive the adjusting member 303 to move up and down, and then drive the clamping wheel 301 to move up and down. When the steel pipe 8 is not detected, the adjusting member 303 moves upward and the clamping wheel 301 is also at the top. After the steel pipe 8 is detected, the adjusting member 303 drives the clamping wheel 301 to move downward, thereby clamping the steel pipe 8. The clamping wheel 301 can be a roller, and the adjusting member 303 can be a rod.

[0048] Preferably, in the preferred embodiment, there are multiple sets of holes on the support frame 1, which can be connected to install at least two driving wheels 6 and at least two clamping devices 3. The simultaneous installation of multiple points allows each cutting point to be well clamped, making it less likely to have accidents during the cutting process, thereby improving cutting accuracy and cutting efficiency.

[0049] More specifically, if Figure 3 As shown, in the preferred embodiment, the motion device 5 includes a motion part 501 and an operating part 502, and the operating part 502 is connected to the motion part 501. The motion part 501 and the operating part 502 can be integrally formed or separately formed, the motion part 501 is a motion platform, which can be a trolley when implemented, and the operating part 502 can be a manipulator when implemented, which can flexibly adjust the position.

[0050] It can be understood that in the preferred embodiment, the moving part 501 is connected with the track 2 and can drive the operating part 502 to move along the track 2, and the laser cutting device 4 is connected to the operating part 502. When the moving part 501 moves along the track 2, the operating part 502 can also move along the track 2, thereby driving the laser cutting device 4 to move along the track 2. At the same time, when the operating part 502 uses a manipulator, it can also flexibly adjust the cutting position, so that the laser cutting device 4 can perform targeted and rapid cutting.

[0051] In more detail, Figure 4 As shown, in the preferred embodiment, the operating part 502 is provided with a camera 7. The camera 7 can automatically identify the length of the defects at the head and tail of the steel pipe 8, which can help cut the steel pipe 8. Further, in the preferred embodiment, the moving part 501 is provided with a laser ranging sensor, which can sense the distance between each other, and the positioning accuracy is not greater than ±0.1mm.

[0052] More preferably, the steel tube laser cutting system in the preferred embodiment further comprises a host computer, which is electrically connected to the motion device 5 and the laser cutting device 4, and the camera 7 and the laser distance sensor connected to the motion device 5 are also electrically connected to the host computer, and the data detected by the camera 7 and the laser distance sensor can be transmitted to the host computer and the host computer gives the next step instruction. The operator can set the cutting program in the host computer in advance, and the motion device 5 can drive the laser cutting device 4 to cut the head and tail of the steel tube 8 according to the cutting length set in the program, and cut it to a fixed length according to the program setting.

[0053] When the steel tube laser cutting system in the utility model is working, the steel tube 8 to be cut is driven by the driving wheel 6 and conveyed to the cutting area of ​​the support frame 1, and the clamping device 3 starts to work, so that the clamping wheel 301 presses down and clamps the steel tube 8 to be cut. The head and tail motion devices 5 on the track 2 drive the camera 7 on the operating part 502 to scan along the outer surface of the steel tube 8 to identify the defect length, and the remaining motion parts 501 drive the laser cutting device 4 to move to the fixed-length cutting point of the steel tube 8 according to the cutting length set by the upper computer. Driven by the operating part 502, the laser cutting device 4 moves horizontally along the cut surface of the steel tube 8 and cuts two layers of the tube wall at the same time. After cutting, the clamping wheel 301 returns to zero, the operating part 502 is reset, the driving wheel 6 sends away the cut steel tube 8, and at the same time transfers to the next steel tube 8 to be cut, and repeats this process until all cutting is completed.

[0054] The steel tube laser cutting system of the utility model introduces a steel tube laser cutting system that can perform multi-point cutting with one clamping, greatly reducing the steel tube cutting cost and improving production efficiency, while the current laser tube cutting machine only uses one laser to cut a single steel tube on the processing platform for cutting the head and tail, and fixed-length cutting requires secondary clamping and must be coordinated with the rotation drive of the steel tube. In addition, the steel tube laser cutting system provided by the utility model is not only compact in structure, but also more convenient for on-site modification and can be applied to a variety of situations.

[0055] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
